Abstract: Time-Mode Signal Processing (TMSP) offers a means for offsetting some of the challenges for analog circuit designs when exploiting CMOS circuit processes designed for digital applications. It would therefore be beneficial to provide a digital method for the storage, addition and subtraction of Time-Mode variables as these offer significant benefit to providing TMSP techniques and expanding their exploitation within devices, systems, and applications. While driven by CMOS process challenges the TM circuits outlined may exploit essentially any digital circuit technology since they are based upon delay. The inventors present an approach to TM variables wherein a switched delay unit is exploited and adopted such that the instantaneous phase difference between two rising signal edges can be latched and used to perform various arithmetic operations. Beneficially, the technique allows analog sampled-data signal processing to be implemented within digital circuitry.

Abstract: Technologies are described herein for providing an automatic reminder function. The technologies are adapted to receive a definition of a reminder as an occurrence or are non-occurrence of an event and to receive operationally relevant data from a system data device. The technologies then determine whether the operationally relevant data indicates that the reminder is triggered by the occurrence or non-occurrence of the event. Responsive to determining whether the operationally relevant data indicates that the reminder is triggered by the occurrence or non-occurrence of the event, the technologies issue the reminder through instrumentation on an aircraft.

Abstract: A priority control unit is provided for use with light-based and GPS-based traffic control priority systems. The priority control unit includes a light emitter subsystem that is configured to emit pulses of light. The pulses of light encode a priority request for activating preemption of a traffic signal by a light-based traffic control priority system. The priority control unit also includes a GPS-based subsystem that is configured to transmit a priority request by radio waves. The priority request from the GPS-based subsystem is for activating preemption of a traffic signal by a GPS-based traffic control priority system. A switch is coupled to the light emitter subsystem and to the GPS-based subsystem. The switch simultaneously activates both the light emitter subsystem and the GPS-based subsystem for transmitting priority requests in response to user control. In another embodiment, the priority control unit further includes a broadcast based subsystem for transmitting priority requests.

Abstract: Tags on documents are clustered using tag weightings of the tags on the documents. Each cluster includes an identified subject. The identified subjects are compared to identify relationships between the identified subjects. A taxonomy of subjects is built using the identified relationships between the identified subjects programmatically without user intervention.

Abstract: A method and a circuit are provided for providing phase or frequency synthesis using sigma-delta modulation bit-stream techniques in which data is encoded utilizing sigma-delta modulation and then digital-to-time conversion (DTC) or digital-to-frequency conversion (DFC). In some embodiments this encoded data stream is further subjected to phase or frequency domain filtering, which in some embodiments is carried out by a higher-order phase-locked loop (PLL).

The standby aircraft management system is associated with the housing and is configured to provide communications, navigation, and control of a number of aircraft systems needed for safe flight and landing of an aircraft in which the standby aircraft management system is located. The backup power system is configured to supply power to the standby aircraft management system when the power is unavailable from the aircraft.

Abstract: A method and system for dispatching calls using a packet network is disclosed. The use of distributed call management modules, enables various communication systems, such as RF and PSTN systems, to communicate with each other over the IP network. Audio devices from the various communication systems are each assigned an IP multicast group. Distributed call management modules covert signals from the audio devices into IP packets and transmit the IP packets to designated IP multicast groups over the IP network.

Abstract: A method and system for generating a taxonomy for documents from tag data are provided. The method includes obtaining tag data in the form of tags on documents with tag weightings for a document and clustering the tags using the tag weightings for documents, wherein each cluster is an identified subject. The documents are associated with each identified subject and the subjects are compared to identifying relationships between subjects to build a taxonomy of subjects. A tag weighting for a document is the number of times the tag is applied to the document with a user rating of the relevance of the tag to the document. The steps are carried out automatically without user intervention.
